European Club Soccer (known as World Trophy Soccer in North America and J-League Champion Soccer (Jリーグチャンピオンサッカー?) in Japan) is a 1992 soccer/football video game by Krisalis Software released for the Sega Mega Drive/Genesis and is mostly based on Manchester United Europe, released one year before for the Commodore Amiga, among other platforms. Like the previously endorsed game, European Club Soccer focus on European competitions, but with only on the European Champions Cup, which can be explained by the lower capacity of the console and the lack of differences between competitions other than the number of teams. If the player won the Champions Cup, the ending credits will only appear if the player beats a South American team in the Intercontinental Cup. The game was a bestseller in the UK charts for three months.
The game allows the player to play friendlies or the Champions' Cup. Options allow choosing game length (from 4 to 90 minutes), difficulty and player change control.
European Club Soccer has dozens of teams from all across Europe (around 170), and each country is represented by at least two teams. In addition to correct club names, it also has recognizable imitations of team badges and kits; although more elaborate kits (such as those worn by Juventus, F.C. Porto or Celtic FC) are simplified (Juventus have a silver shirt, Porto blue and Celtic green). Player names, on the other hand, were made by mixing names found on real squads. Portuguese teams, for instance, had a large number of Yugoslavian players in the early 1990s, and that was reflected by players with names such as Valentim Ivic (of Valentim Loureiro and Tomislav Ivic, then Boavista FC chairman and S.L. Benfica manager, respectively). Names could not be changed, and since the game lacked a battery, it does not store changes done to kits and passwords were used to resume tournaments (example of a password sheet). Rotherham United are included amongst the English clubs despite never playing in the top tier of English football, this is due to the developer, Krisalis Software, being based in Rotherham. All other clubs have played in their own country's top tier.
